2 Claims.

This invention relates to fluid dispensers, and aims to provide a devicebyl means of which a mixture of two fluids commonly used as a syrup andsoda water, or a liquor and soda water, may be selectively orsimultaneously passed into a container, such asa glass, the quantity ofthe syrup or liquor thus dispensed being predetermined by the setting ofa regulating means forming part of the device. V

The above and other objects will become apparent in the descriptionbelow in which characters of reference refer to like-named parts in.

the accompanying drawings.

Referring briey to the drawings, Figure l f is a side elevational viewof the device.

Figure 2 is a bottom plan view of the same.

Figure 3 is a cross-sectional view taken on the line 3-3 of Figure 1.

Figure 4 is an erected cross-sectional view taken on the line 4-4 ofFigure 2, showing the liquor regulating means in one position.

Figure 5 is a fragmentary cross-sectional view of the liquor chamber, ofFigure 4, showing the liquor regulating means in another position.

Figure 6 is a fragmentary side elevational View of the device, partly insection, and showing the liquor regulating means in a third position.

Referring in detail to the drawings, the numeral IDVindicates atransparent cylinder having screw caps I I and I2 at the top and bottom,respectively, these members enclosing the syrup or liquor chamber I3.The caps II and I2 have axially aligned threaded openings I4 and I5,respectively, therethrough.. A tube I6, threaded on both its exteriorand interior surfaces, projects threadably downward through the openingI4 and has a knurled ring Il on its upper end. A tube I8, threaded onits exterior surface only, projects upward through the opening I5, andhas a knurled ring I9 on its lower end. A packing nut I2a surroundingthe tube I8 is turned up against the cap I2, Within the upper tube I6, athinner tube 20, with threads on its outer surface only, is inthreadable engagement with the inner threads of the tube I6. A tube ZI,having its interior surface smooth throughout and its exterior surfacesmooth except for threads 22 on the lower end of its exterior surface,is slidably mounted within the tube I8. A smooth-surfaced tube 23,having a'collar 22 at a point nearer its upper end, is slidably mountedwithin the tubes CSI 20 and 2l, with the collar 24 positioned betweenthe adjacent extremities of the tubes 20 and 2I and serving as a limitstop in the approach of the latter tubes toward each other. It is to benoted f that the tube 2l has a flange 25 on its upper end, whichoverlaps the upper end of the tube I8. Just above the collar 24, atransverse opening 26 passes diametrically through the tube 23, and asimilar opening 21 is provided just below the collar. The threaded end22 of the tube ZI projects through and threadablyv engages an opening ina horizontal brace or support 28. A knurled nut 29, having a smoothopening therethrough,

through which the tube 23 projects slidably, is

screwed on the end 22 of the tube 2|, and retains the brace 28 betweenthe ring I9 of the tube I8 and itself. Near its lower extremity the tube23 has a shoulder 30 from which the reduced stem 3l of this tubeprojects through an opening 32 in a member 33 described below. The lowerextremity of the stem 3| is threaded, and a knurled nut 34 limits themember 33 to movement between Ythe latter nut and the shoulder 30. Y Acoiled spring 35 normally urges the member 33 awayv edgescrew threaded,Vand being further providedv with an internal shoulder 38. A tube or`stem 39 is slidably mounted in the tit 3B and the head 4Q on its upperextremity is adapted to rest on the shoulder 38. A knurled nut 4Isurrounds the projecting end ofthe tit 36, and the stem 39 projectsslidably through a smooth central opening therein. The construction ofthe lower end of the stem 39 is similar to that of the lower end of thetube 23, the shoulder being shown at 30a, the reduced portion at 42, andthe nut on the end at 44, the opening in the member 33 through which theportion 42 projects being shown at 43, and the spring at 35a,

A cylinder 45 is provided with a threaded tit 4B which registers in thethreaded upper end of the housing 3l. The upper end of the cylinder 45also has a threaded tit 48 which is engaged by a knurled nut 49 having asmooth opening through its center. The cylinder 45 has a smooth axialchannel in which a tube 50 is slidab-1e.- The upper end of the tube 50is widened to form a neck 5I having external threads on its upperextremity. The upper peripheral surface of the cylinder 45 is alsoknurled, as shown at 53. The stem 39 has a transverse opening 54 justbelow its head 40, extending diametrically through the stem.

The device is held in upright position suitable means, not shown. A hoseor pipe, not shown, leading from a source of liquor, syrup or other uidsupply, is connected to the top of the tube 20. A second hose or pipe,not shown, leading from a tank containing carbonated orY soda. water, isconnected to the top 5.2 of the tube 5B. The member 33 serves as ahandle or lever which'is operated by pushing either end thereof upward,or the entire member upward at once. It is obvious that when the righthand end (Figure 4) is pushed upward a suicient disby any E tance toraise the opening 34 of the stem 39 clear of the shoulder 38, the sodawater will pass from the housing 31 through the stern` 39 and outthrough the lower end of the stem.

In Figure 5, both openings 26 and 21 are shown closed; hence, assumingthat the flow of syrup into the top of the tube is on, the same Will bechecked at the opening 26 by the lower periphery of the tube I6 and thecollar 24. This is the condition in which the device may be kept Whennot in use, as, for instance, over night, and is attained by screwingdown the nut I1 (since the tube 20 is permanently attached to the syrupconduit or pipe, it will not be rotatable thereafter). To place thedevice into condition for use as a dispenser, the nut I1 is screwedupward until the lower edge of the tube I6 rises clear of the upperopening 2t in the tube 23, as shown, in Figures 1 and 4, which also showthe lower opening 21 closed by the upper end of the tube 2I. When theupper opening 26 is thus freed, syrup will be Vfree to pour down throughsaid opening and into the chamber I3. To permit the syrup to flow intothe chamber, the left hand end of the lever 33 is pushed upward (andheld in that position) a suicient distance to partly unseal bothopenings 23 and 21. When the lever in the chamber rises above the lowestpoint of the opening 21, it will ow down the tube 23 below the collar2d, and as soon as it begins to ow out at the bottom of the tube 23, thelever 33 is released, the spring 35 then causn ing it to draw down thetube 23 and seal the opening 21 while fully unsealing the opening 26.

through the opening 23 until the air at the top of the chamber will havebeen compressed to a` point at which its. pressure equals that of theincoming syrup, and then the incoming flow will stop, a level somewhatabove the uppermost point of the opening 26. The flowing syrup may begiven a sufficient pressure by a force pump or by gravity.

In use, a glass is held under the device with its rim surrounding bothnuts 34 and M. The left hand end of the lever 33 is pushed up, thusunsealing the opening 21. The escape of the syrup through the opening 21will be enhanced at iirst by the pressure of the trapped air, mentionedabove. The lever is held in that position until the level of the syrupin the chamber has fallen to the level of the lowest point of theopening 21, at which time the outward flow Will stop. The pressureagainst that side of the lever is then released and the right hand sideof the lever is then pushed up thus causing soda water to flow into theglass, as previously described, the latter flow being stopped when thedesired amount has been dispensed, by simply releasing the lever. Ifboth ends of the lever are moved together, the limited quantity ofsyrup, above mentioned, will flow into the glass, and the soda waterwill ow simultaneously. If desired, the lever could be operated byapplying the rim of the glass thereagainst.

The amount of syrup represented by the volume or" the disc between thetopmost level (where the air pressure balances the incoming syruppressure) and the bottonunost level (the lowermost level of the opening21) is the portion dispensed each time the glass is thus applied to theleft hand end of the lever. When the left hand end of the lever has beenpermitted to fall, as just mentioned, with the consequent sealing of theopening 21 and unsealing of the opening 26, the incoming syrup willagain flow into the chamber to the same level mentioned above, at whichthe air pressure balances the syrup pressure. Thus,

`each portion of syrup thus dispensed will be of the same volume. If itis desired to reduce the volume of each portion, the nut I1 may bescrewed down', so as to reduce the area of the opening 26 when the tube23 is in raised position by bringing the lower edge of the tube 2Upartway down across the said opening.

It is obvious that a combination dispenser of both syrup and soda water,or any other desired combination of fluids, has been provided,possessing the many useful and practical features which need not bementioned specifically.

Obviously, modications in form and structure may be made withoutdeparting from the spirit and scope of the invention.
